流动注射分析(FIA)作为一种灵活高效的试样一试剂溶液处理手段与原子吸收光谱分析联用显著地扩展了后者的应用前景。氢化物发生-原子吸收流动注射分析(HGAAS-FIA)作为这类联用技术以其显著的特点引起了人们的注意。本文拟将数年来的文献和作者的实践作一概述。实验装置及分析技术氢化物发生-原子吸收流动注射分析的工作原理是:将一定体积的试样溶液(数十至数百微升)注入到连续流动的载流(去离
Flow injection analysis (FIA) as a flexible and efficient sample-reagent solution treatment method in combination with atomic absorption spectrometry significantly expands the application prospects of the latter. Hydride Generation - Atomic Absorption Flow Injection Analysis (HGAAS-FIA) has attracted the attention of people for its remarkable features as a combination of these technologies. This article is intended to summarize the literature over the years and the author’s practice. Experimental Setup and Analytical Techniques Hydride Generation - Atomic Absorption Flow Injection Analysis works by injecting a volume of sample solution (tens to hundreds of microliters) into a continuous flow of carrier gas
